jsp实现仿QQ空间新建多个相册名称并向相册中添加照片功能

2024-02-25 21:51:03 293

工具：Eclipse，Oracle，smartupload.jar；语言：jsp，Java；数据存储：Oracle。

实现功能介绍：

主要是新建相册，可以建多个相册，在相册中添加多张照片，删除照片，删除相册，当相册下有照片时先删除照片才能删除相册。

因为每个相册和照片要有所属人，所以顺带有登录功能。

声明：只是后端实现代码，前台无任何样式，代码测试可行，仅供参考。

代码：

数据库连接帮助类：

publicclassJDBCHelper{
publicstaticfinalStringDRIVER="oracle.jdbc.driver.OracleDriver";
publicstaticfinalStringURL="jdbc:oracle:thin:@localhost:1521:xxxx";
publicstaticfinalStringDBNAME="scott";
publicstaticfinalStringPASSWORD="xxxx";
publicstaticConnectiongetConn()throwsException{
Class.forName(DRIVER);
Connectionconn=DriverManager.getConnection(URL,DBNAME,PASSWORD);
returnconn;
}
}

图片上传时，要修改图片名称，防止上传重名图片将上一张覆盖，这里的做法是将图片名改为由用户ID和精确到毫秒的时间组成，修改图片名的帮助类：

publicclassPhotoName{
privateStringip;
publicPhotoName(Stringip){
super();
this.ip=ip;
}
publicStringgetIp(){
returnip;
}
publicvoidsetIp(Stringip){
this.ip=ip;
}
publicStringgetTime(){
Datedate=newDate();
DateFormatdf=newSimpleDateFormat("yyyyMMddHHmmssSSS");
returndf.format(date);
}
publicStringgetPhotoName(){
returnthis.ip+this.getTime();
}
}

实现所有这些的接口类：

publicinterfaceUpDAO{
/**
*创建相册名称
*
*/
publicintcreAlbum(AlbumPOJOap);
/**
*显示所创建的所有相册名称
*/
publicListfindAllAlbum(intid);
publicListfindAllPhoto(intid);
/**
*上传照片
*/
publicintupPhoto(PhotoPOJOpp);
/**
*删除相册
*@paramid相册id
*@return
*/
publicintdelAlbum(intid);
/**
*删除照片
*@paramid照片id
*@return
*/
publicintdelPhoto(intid);
/**
*登录
*@paramusername
*@parampassword
*@return
*/
publicUserPOJOlogin(Stringusername,Stringpassword);
}
